WALTHER FELD, OF HONNINGEN-ON-THE-RHINE, GERMANY. APPARATUS FORSUBJEOTING GASES TO THE ACTION OF LIQUIDS- Specification of LettersPatent.

Application filed December 15, 1905. Serial No. 291.902.

To all whom it may concern:

Be it known that I,WALT1IER FELD chemist and manufacturer, a subject ofthe King of Prussia, German Emperor, residing atIIonningcn-on-thc-Rhine, in the German Empire, have invented new anduseful Improvements in Apparatus for subjecting Gases or Va ors to theAction of Liquids, of which the to lowing is a Specification.

This invention has for 1ts ob'cct to provide improved apparatus by whicgases or vapors (such, for instance, as illuminating-gas and gases andvapors from coke-ovens, gasproducers, blast furnaces, exhaust from steamor gas engines, steam from evaporators, and the like) are veryeiiiciently subjected to the action of liquids which may be of anysuitable description, such as solutions with or without agents suspendedtherein or liquids resulting from the condensation of vapors from thegases, or it may be water, oil, tar, or the like.

According to this invention the apparatus consists of or comprises acasing containing a vessel or vessels for the liquid, between whichvessel or vessels and thp casing is a space for the passage of gas andin and above the said vesselor each vessel is a rotatable deviceconsisting of two or more concentric pipes for dipping into the liquidin the said vessel or vessels and extendin above the said liquid, sothat on rotation the said pipes will under centrifugal action take uponly liquid between them and distribute it in the form of spray acrossthe whole of the space throu h which the gases or vapors pass, so that t6 game pass only through sprayed liquid. here may also be rovided meansfor returning the s rayed liquid into the vessel or vessels, so that itcirculates through the spraying device or devices, and a filter ma beprovided for separating moisture whicli the gases or vapors may havetaken up from the spra ed liquid.

In or er that this invention and how it may be performed ma be wellunderstood, I wil describe, with re erence to the accompanying drawings,arrangements in accordance therewith.

Figure 1 is a vertical section of one form of the apparatus, and Fig.2is a vertical section of a modification.

Referringlfirst to the construction shown in Fig. 1, t e apparatusconsists of a casing A, containing a number of superposed vessels B,with a space between their outer sides and the casing A, the saidvessels B holding the liquid. The said vessels B may be rovided with anysuitable overflows (suc as those at b) to the vessel B beneath and alsowith any suitable arrangements of cleansin valves or openings and doors.Above eac vessel B is an inclined funnel C, secured to the casing atits'upper edge and with its lower edge directed to within the vessel Bbeneath. Passing down through the center of the apparatus is a rotatableshaft D, connected with which are concentric ipes e, dipping into theliquid in the vessel ii, the said pi es e being arranged one within theother, so t at there are spaces between them for the passage of liquidonly up between the said pipes e and onto and off the said annularplates E, one carried by the upper art of each i e, the said passage ofliquid being induced y centrifugal action due to the motion of rotationgiven to the said pipes e and annular lates E when the shaft D isrotated, the li uid bein under such centrifugal action t own 0 from thesaid annular plates, so as to form a fine spray of the said iquidthroughout the whole of the cross-sectional area of the space betweenthe said annular plates E and the interior of the aforesaid funnel C,the gases or vapors entering from below at F and passing up, as shown bythe arrows,) the spaces between the outsides of the vessels B and theinside of the casing A, then between the edges of the said vessels B andof the inclined funnels O and u through the aforesaids aces in which theiquid is sprayed, as a oresaid, Where the said gases or vapors are verythorou hly subjected to the action of the sprayed liquid, passing, asthey do, through sprayed liquid only. After the said gases or vaporspass from the uppermost divsion of the apparatus the pass through afilter G which is preferab y annular or cylindrica and arrangedvertically,.as shown, inside the upper Ipart of the casing A,deflecting-surfaces being arranged so that the gases or va orsarecompelled to' pass through the said filter G into the space betweenit and the casing and thence to the outlet I, the said filter Gseparating any liquid which may be carried up with the gases or vapors.The liquid can be admitted to the u per vessel through any suitableinlet an pass off through an outlet beneath the vessel. The lates E areshown with rims but these can e omitted, as can also the said plates, asillustrated in the modification lowermost shown in Fig. 2, in which thevessels B are made of somewhat conical shape, and the overflow-passagesare outside, as shown at b, and may be formed by a removable 'utter, thepipes e beiru made more flaring t an in Fig. l. The action of this formof the apparatus is generally like that of the form shown in Fig. 1, andcorresponding parts are marked with the same letters of reference, andin the following claims I mean by pipes such pijies whether providedwith plates E or not.

nstead of the gases or vapors being passed upward through the casingthey may be passed downward therethrough, in which case the inlet forthe gases or vapors will be at the upper part of the casin and theoutlet for the gases or vapors will be below the lowermost vessel B, andthe filter will be placed between the said lowermost vessel B and thesaid outlet.

The funnels C and overflows from the vessels B enable a constantcirculation of the liquid to be maintained. Surplus liquid which may berun in at the to of the apparatus or which may condense from the gasesor vapors can leave or be drawn from the apparatus by a sealed outlet orvalve at bottom.

There maybe any suitable number of the arrangements of vessel andspraying devices, as described, and the casing can be conveniently madeup of sections each carryin r such an arrangement and superposed anluted together, as illustrated.

Havin 7 now particularly described and ascertainet the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. Apparatus for subjecting gases, or vapors, to theaction of liquid, the said ap aratus comprising a casing with an inletan out let for the gases, or vapors, a vessel to contain the liquid and.a rotatable shaft having secured to, and surrounding, it, two, or more,concentric pipes, one within another and with the passage for gases, orvapors, surrounding their upper parts, and with their lower endssituated in the vessel for liquid, and means for rotatin' the said shaftand pipes to take up onl liquid between them and distributeit in t ieform of spray across the said surrounding passage for gases, or vapors.

2. An apparatus for subjecting gases, orva pors, to the action ofliquid, the said apparatus comprisin a casing having an inlet and anoutlet for t e gases, or vapors, superposed vessels to contain theliquid, overflow-passages from the vessel above to the vessel beneath,inclined surfaces connected at top with the casing and terminating over,or within, the said vessels, and a central rotatable shaft for eachvessel, carrying concentric pipes having the passage for gases, orvapors, surrounding their upper parts and having their lower ends in thevessel for liquid so that on rotating the shaft the said pipes, un dercentrifugal action, take up only liquid between them and distribute itin the form of spray across the surrounding space through which thegases, or vapors, pass, the s rayed liquid being returned to the vesselsiy the aforesaid inclined surfaces.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

WALTHE R FELD.
